Product Highlights

  • 180mm Aperture Maksutov-Cassegrain OTA
  • 2700mm Focal Length, f/15 Focal Ratio
  • Limited-Diffraction Optical System
  • Anti-Reflection Fully Multi-Coated Glass
  • Internal Primary Mirror Focusing System
  • 28mm Long Eye Relief 2" Eyepiece
  • 2" 90° Star Diagonal
  • 8x50 Straight-Viewing Finderscope
  • Vixen-Style Dovetail Plate

With the largest aperture in the series, the Sky-Watcher 180mm f/15 Maksutov-Cassegrain Telescope is a powerful astronomical tool that remains manageable and portable. The Maksutov design exchanges the conventional front corrector plate of a Schmidt with a convex meniscus lens, resulting in a smaller secondary mirror that limits obstruction and increases contrast, while eliminating the need for periodic collimation. This modified optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt, but the optical benefits, when coupled with the larger aperture and fully multi-coated optics, make this an ideal scope for making detailed solar, lunar, and planetary observations, while being able to resolve deep-sky objects like stars, clusters, galaxies, and nebulae.

The scope is outfitted with a large 2" visual back. To get users started, Sky-Watcher includes a 28mm long eye relief eyepiece that produces 96x magnification and a 90° star diagonal for viewing with the optical tube assembly (OTA) pointed at or near the celestial zenith. The OTA is offered here without a mount or tripod for users who have a reliable support system or want to use it as part of a dual-OTA setup for star parties or observation/imaging rigs. It is outfitted with a Vixen-style dovetail plate for use with compatible mounts. This OTA's compact form factor belies its observation power and resolution and is ideally suited as a grab-and-go option for quick observation sessions or heading out to remote locations.

Optical Performance
  • 180mm aperture
  • f/15 focal ratio
  • 2700mm focal length
  • Front convex meniscus lens corrects spherical and chromatic aberrations as well as comas (off-axis aberrations) across the entire field of view
  • Smaller secondary mirror versus Schmidt-Cassegrains reduces obstructions and increases contrast
  • Fully multi-coated optics maximize light transmission to improve brightness, color rendition, sharpness, and contrast
  • Resolution: 0.64 arcsec
  • Internal primary mirror focus
  • 2"-diameter visual back accepts larger eyepieces and accessories
Mounting
  • Requires mount and tripod for proper use
  • Vixen-style dovetail plate
  • Weight: 19 pounds including OTA, dovetail plate, finder, diagonal, and eyepiece
Included Accessories
Eyepiece:
  • 2" barrel diameter
  • Accepts most 2" astronomical filters
  • 28mm eyepiece yields 96x power
  • Comfortable long eye relief

Diagonal:

  • 2" snout and eyepiece holder
  • 90° angle places head in a comfortable viewing position
  • Star configuration corrects image horizontally for terrestrial use

Finderscope:

  • Relatively low 8x magnification provides a wide field of view for easier alignment and faster star-hopping navigation
  • 50mm aperture helps resolve dimmer objects that dot finders cannot
